Those birds can be rehydrated by an experienced taxidermist and mounted with no trouble for years. Of course he will want them sooner rather than later. I would say flying backs out as a pair would be very striking but am personally found of standing with one foot lifted. When the foot lifts it lofts the wing out of the sidepocket and shows off that pretty wing patch.
There is no help for this kind of insanity. I'm just a duck hunter, and should not be held accountable for all my actions between October 1st and freeze-up. Gordon MacQuarrie
